FRENZ AI Sleep Science 4+

I’ve always wanted to improve my sleep quality so I’ve tested out a variety of sleep trackers over the years, ranging from the old-fashioned journaling method to wrist-worn wearables. While they have their perks of continuous data trend, they also come with many limitations. Wrist trackers mainly measure things like arm movements and heart rate variability, but I’ve notice the inconsistencies between their data and my own behaviour. I even went extra miles by wearing both Oura and Garmin simultaneously for camparison (yeah I’m dedicated), and found that their reports often differentiated the most for my deep sleep duration and REM sleep duration. Then I also tried EEG trackers but none of them offered the real-time intervention methods like Frenz. Althought I’m still skeptical about their 89% accuracy compared to PSG in the sleep lab, this is the most accurate gadget I have found on the market with my sleep behaviour. I have noticed after a few days my deep sleep duration is slightly increasing with their deep sleep boosting feature. I do feel better over each day and still keep my sleep journal for my own experiment purpose. I would recomend everyone who want to purchase this band to read more about CBT-i audio techniques and how it works, so the slaudio voice can have better impact on your brain. From my own experience of listening to Calm and Headspace over the years, Frenz’s sleep audio content actually has better effect on me.

A colleague introduced me to Frenz, and it was as if a veil had been lifted. Skeptical at first, I decided to approach it with the same rigor and objectivity I apply to my scientific inquiries. To my surprise, the results were astounding.
The binaural beats, backed by extensive research and empirical evidence, have a profound effect on brainwave patterns, inducing a state of deep relaxation and promoting the onset of restorative sleep. The voice coaching, grounded in proven mindfulness and meditation techniques, effectively quiets the incessant chatter of the mind, allowing for a seamless transition into a peaceful slumber.
As a result, my sleep quality has dramatically improved, leading to enhanced cognitive function, increased productivity, and a greater sense of overall well-being. The impact on my work has been substantial, enabling me to approach complex problems with renewed clarity and creative insight.

After almost one year of waiting I got the band and I’m extremely disappointed. The app is ok, it shows “raw” data but you can’t really tell type of brainwaves is reading or the intensity ( delta, theta, beta, alpha waves). There is a basic list of guided meditations and soundscapes. The volume of the meditations is constant and not impacts by your brainwaves. So it works the same as any meditation app. —-the band—- The bone conduction speakers can nearly be heard at max volume. it improves if you wear noise canceling ear plugs but then it gets loud on the ear if you sleeps sideways, so it isn’t consistent. The signal quality based on the app is consistently bad. I have short hair and I haven’t been able to get a good reading on the band. I’ve spent over 30 min trying it to get it to work and I’ve failed. —customer support It is pretty slow and sometimes fully unresponsive. Any inquiry on the chat in the morning or night US time is responded 24 hours or more later. So I’m not sure why they have a chat functionality, they might as well offer an email functionality so as a customer you know to include all the details of your question at once. I’m hoping that my bad is defective and customer support will eventually get back to me and that the band works better. But so far non of the promises on delivery time, and product quality have been delivered :(
